- To all whom lit may concern: l

Be it known that I HENRY. CLnrrnNs, a citizen of the United States, resldmg iat Manitowoc, in the .coun of Manitowoc and- State of Wisconsin, have invented new and useful Improvements in Box-Openers, of

which the :following is a specification.

lfhis'I invention relates to box openers es- Ieeiallydesigned for use in connection with .such boxes as those containing shoe aste and the like, wherein :the `cover ,is eld tightly upon *the box'to prevent evaporatlpn A of its conten ,and consequently very difficult to remove. L 0 l It has been found that 1n Ydevices of this nature, where a studjnarrying the lifting element is journale man opening 1n the body portion-ofthe box', that theV stud after being rotated a fewtirnes enlarges the openl' 20 ing, thus causing evaporation of the contents ofthe box, thisbeing essentially true with boxes of the abovev mentioned character. y

XIt iis the object of .this invention to overcome the above noted objections by "mounting the stud infxed relationv to the boxfin such manner that the opening therein will be closed, and having the cover lifting element rotatably mounted thereon y Among otherfeatures which will appear, the invention resides in the specific con-A struction, combination and arrangement of parts hereinafter more fully described. y .In the drawing forming a .part of this application like numerals of reference indicate similar parts in the several views and in which Figurev 1 is a perspective view `of the box "with my device applied. Fig. 2 is a view of. .49 "the box with the cover partly removed show-` ing the manner of using the device. Fig. 3

1s a planview with the cover removed. Fig.

4 is a detail view of the pivot stud/and key.

Referring. to the drawing in detail 5 des- Ligr r'ates the body portion of a box having van annular bead 6, the cover bein indicated at 7 having a flared marginal e ge portion 8 for engagement with the bead 6 when in position on the box. The bead 6 and the 5.0 fiared portion 8 of the'cover are cut awayy as at 9 to permit the device forming the subject matter of my invention to `be operatively associated beneath the marginal edge portion of the cover.

The device comprises a. pivot stud 10 which projects from the sida-- of the box 5 f Box-onnNnn y l Specification of Letters PatentA ,Apyucafignhia october so, 1914. serial No. 869,442.

at av point immediately above the cut away s portion 9 of the bead 6, and upon the latter is mounted for-rotation a key 11. The stud is rovidcd with a reduced end portion 12 extnded through a suitable opening in the side of the vbox 5 and upturned against the inner.face thereofwith a view of closing .the opening. The reduced portion 12 de- Ilines a shoulder 13 which engages the outer surface of the box, and between which and the flattened extremity of the stud, the latter4 is mounted uponv thebox in xed relation thereto. ,By reason of this construction and arrangement it will be noted that the opening in the box through which the stud 10 extends, is at all times effectively closed thereby preventing evaporation of the contents of the box.

Mounted for rotatie-n upon the pivot stud 10 is a cover lifting element 14 in the nature of a keyy constructed from a substantially elongated piece ofmeta-l slit longitudinally through the center at spaced points 16, the strips 17 formed by the slits being alternately bent in opposite directions to form bearings for the reception of the stud 10, the latter being headed as at 18 for engagement with the outer edge of the key to prevent casual separation of` the members.

Projecting centrally from the inner edge of the' nger'` portion ofthe key and arranged at opposite sides ofthe stud are' lugs 19 which underlie thema'rginal edge of thev cover, and adaptedt'o force the latter upwardly from the box upon rotation of they key. The device is extremely simple in con- Q struction and while 'I have shown and described the same as being'primarily intended for use in -conjunction with blackening boxes, I desire to have it understood that it is susceptiblefor 'use with boxes of dierent contours and dimensions;'

It is believed that/.from the foregoing dej scription the nature andV advantages ofthe invention Ywill .be readily understood withoutv requiring a m'refextended explanation and therefore the same has been omitted.
